COVID-19 Variants
SARS-CoV-2 (the virus that causes COVID-19) evolves over time, which results in a new strain (variant) of the virus. With COVID-19, new variants continue to emerge, with some variants disappearing while others will persist. The SARS-CoV-2 variants are classified into four groups: new variants of concern, variants of high consequence, variants being monitored and variants of interest. The AMA has developed FAQs and resources that look at the latest COVID variants of concern and guidance on how many COVID variants are there.
